Better than expected. Used it to bring a functionally dead dehumidifier back to life.

I have an Amazon Basics 50pt humidifier that after 3 years became non functional... it ran, but no moisture would be collected. So I purchased this retrofit valve to tap into the refrigerant line.At first puncture, I noticed the dehumidifier was completely empty. I mounted this on one of the joint points (since the metal is a bit thicker there), then refilled it with automotive R134a, and bam! I was back in business. This plus a can of R134a helped revive that $300 humidifier and save it from the landfill.I was a bit concerned about the temporary valve being too "temporary" and leaking, but a retest of the system after a few weeks showed almost no detectable leakage so I think I'm good there!I gave it 4 (out of 5 stars) due to the valve not being very secure on the install point. It wobbles quiet a bit. Because of this, I didn't retract the puncture pin leaving it partially in the hole it created just to keep the valve aligned.... not the best approach, but it looks like it worked.

This works great.

Had to tap into my 5cf chest freezer after modifying it into a water chiller I had to refill it because I nicked a Freon line. Stuck a small piece of aluminum tape over the hole I drilled and then used JB clear weld epoxy and let it cure a three days before adding another layer of epoxy. Let it cure another week, installed this valve, pulled a vacuum, saw it held, charged it and it actually works better than when we stored food in it.Something to note is that when you’re done re charging be sure to close the piercing valve all the way. This adds an extra barrier to seal before the shredder valve. I don’t have any leaks.

There are not two tap kits in the package as the description implies. I was tricked.

There are not two tap kits in the package as the description implies. I was tricked. The description implies you get two for $9.xx. Not true. One kit... one tap and the 134a adapter.... the Schrader value core remover is included as well.
